Six primitives. One gateway.

Each works on its own. Together they replace the model-routing layer for every app you ship.

Model Groups

Package backends, models and routing policy behind one stable name your app calls directly.

Routing

Single-backend, weighted load-balancing, fallback, or conditional routing by request metadata.

Multiple Providers

OpenAI, Anthropic, DeepSeek, OpenRouter and any custom OpenAI-compatible service.

Coding Plans

Run coding-plan backends beside credit-based keys, with quota and balance visibility.

Thinking Output

One reasoning request format; read standardized reasoning text across every model.

Usage & Billing

Track spend and tokens per group, key and customer tier in a single console.

Failover before your users notice.

Define a policy once. The gateway evaluates weights, retries, and fallbacks on every request — and hands back a standardized response no matter which backend answered.
